taken by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient 



                                       8

or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his

or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

         The ownership of Securities shall be proved by the Security Register.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the

transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

         The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities of the relevant series on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 106.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to



                                       9
   18

institute proceedings referred to in Section 507(2) or (iv) any direction
referred to in Section 512, in each case with respect to Securities of such
series. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities of such series on such record date, and no other Holders,
shall be entitled to join in such notice, declaration, request or direction,
whether or not such Holders remain Holders after such record date; provided that
no such action shall be effective hereunder unless taken on or prior to the
applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date. Nothing in this
paragraph shall be construed to prevent the Trustee from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

         With respect to any record date set pursuant to this Section, the party
hereto which sets such record date may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the then existing Expiration Date. If an Expiration
Date is not designated with respect to any record date set pursuant to this
Section, the party hereto which set such record date shall be deemed to have
initially designated the 180th day following such record date as the Expiration
Date with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date
shall be later than the 180th day following the applicable record date.

         Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

Section 105.     Notices, Etc., to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver

              (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at the address of its principal
         office specified in the first paragraph of this instrument or at any
         other address previously furnished in writing to the Trustee by the
         Company.

Section 106.     Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

Section 107.     Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act or with another provision hereof which is required
under the Trust Indenture Act to be a part of and govern this Indenture, the
latter provisions shall control. If any provision of this Indenture modifies or
excludes any provision of the Trust Indenture Act which may be so modified or
excluded, the latter provision shall be deemed to apply to this Indenture as so
modified or to be excluded, as the case may be.

Section 108.     Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

Section 109.     Successors and Assigns.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

Section 110.     Separability Clause.

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 111.     Benefits of Indenture.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

Section 112.     Governing Law.

         This Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York.

Section 113.     Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) payment of interest or principal
(and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity.

         multiple thereof the denominations in which any Securities of the
         series shall be issuable;

              (10) if the amount of principal of or any premium or interest on
         any Securities of the series may be determined with reference to an
         index or pursuant to a formula, the manner in which such amounts shall
         be determined;

              (11) if other than the currency of the United States of America,
         the currency, currencies or currency units in which the principal of or
         any premium or interest on any Securities of the series shall be
         payable and the manner of determining the equivalent thereof in the
         currency of the United States of America for any purpose, including for
         purposes of the definition of "Outstanding" in Section 101;

              (12) if the principal of or any premium or interest on any
         Securities of the series is to be payable, at the election of the
         Company or the Holder thereof, in one or more currencies or currency
         units other than that or those in which such Securities are stated to
         be payable, the currency, currencies or currency units in which the
         principal of or any premium or interest on such Securities as to which
         such election is made shall be payable, the periods within which and
         the terms and conditions upon which such election is to be made and the
         amount so payable (or the manner in which such amount shall be
         determined);

              (13) if other than the entire principal amount thereof, the
         portion of the principal amount of any Securities of the series which
         shall be payable upon declaration of acceleration of the Maturity
         thereof pursuant to Section 502;

              (14) if the principal amount payable at the Stated Maturity of any
         Securities of the series will not be determinable as of any one or more
         dates prior to the Stated Maturity, the amount which shall be deemed to
         be the principal amount of such Securities as of any such date for any
         purpose thereunder or hereunder, including the principal amount thereof
         which shall be due and payable upon any Maturity other than the Stated
         Maturity or which shall be deemed to be Outstanding as of any date
         prior to the Stated Maturity (or, in any such case, the manner in which
         such amount deemed to be the principal amount shall be determined);

              (15) if applicable, that the Securities of the series, in whole or
         any specified part, shall be defeasible pursuant to Section 1302 or
         Section 1303 or both such Sections and, if other than by a Board
         Resolution, the manner in which any election by the Company to defease
         such Securities shall be evidenced;

              (16) if applicable, that any Securities of the series shall be
         issuable in whole or in part in the form of one or more Global
         Securities and, in such case, the respective Depositaries for such
         Global Securities, the form of any legend or legends which shall be
         borne by any such Global Security in addition to or in lieu of that set
         forth in Section 204 and any circumstances in addition to or in lieu of
         those set forth in Clause (2) of the last paragraph of Section 305 in
         which any such Global Security may be exchanged in whole or in part for
         Securities registered, and any transfer of such Global Security in
         whole or in part may be registered, in the name or names of Persons
         other than the Depositary for such Global Security or a nominee
         thereof;

              (17) any addition to or change in the Events of Default which
         applies to any Securities of the series and any change in the right of
         the Trustee or the requisite Holders of such Securities to declare the
         principal amount thereof due and payable pursuant to Section 502;

              (18) any addition to or change in the covenants set forth in
         Article Ten which applies to Securities of the series; and

              (19) any other terms of the series (which terms shall not be
         inconsistent with the provisions of this Indenture, except as permitted
         by Section 901(5)).

         All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and (subject to Section 303) set
forth, or determined in the manner provided, in the Officers' Certificate
referred to above or in any such indenture supplemental hereto.



                                       21
   30

         If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

Section 302.     Denominations.

         The Securities of each series shall be issuable only in registered form
without coupons and only in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination
with respect to the Securities of any series, the Securities of such series
shall be issuable in denominations of $1,000 and any integral multiple thereof.

Section 303.     Execution, Authentication, Delivery and Dating.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its President or one of
its Vice Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities as in this
Indenture provided and not otherwise. If the form or terms of the Securities of
the series have been established by or pursuant to one or more Board Resolutions
as permitted by Sections 201 and 301, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee shall be entitled to receive, and (subject to,
Section 601) shall be fully protected in relying upon, an Opinion of Counsel
stating,

              (1) if the form of such Securities has been established by or
         pursuant to Board Resolution as permitted by Section 201, that such
         form has been established in conformity with the provisions of this
         Indenture;

              (2) if the terms of such Securities have been established by or
         pursuant to Board Resolution as permitted by Section 301, that such
         terms have been established in conformity with the provisions of this
         Indenture; and

                                       22
   31

              (3) that such Securities, when authenticated and delivered by the
         Trustee and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel win constitute valid
         and legally binding obligations of the Company enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture in accordance with the Board Resolutions will affect
the Trustee's own rights, duties, obligations, responsibilities or immunities
under the Securities and this Indenture or otherwise in a manner which is not
reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary, unless the Trustee reasonably determines
otherwise, for the Company to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

Section 304.      Temporary Securities.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

                                       23
   32

         If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

Section 305.      Registration; Registration of Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office or
other designated office of the Trustee a register (the register maintained in
such office being herein sometimes collectively, referred to as the "Security
Register") in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of Securities and of transfers of
Securities entitled to registration or transfer as provided herein. The Trustee
is hereby appointed "Security Registrar" for the purpose of registering
Securities and transfers of Securities as herein provided.

         Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Company in a Place of Payment for that series,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Securities
of the same series, of any authorized denominations and of like tenor and
aggregate principal amount.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.



                                       24
   33

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

         If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Company shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103 and
ending at the close of business on the day of such mailing, or (B) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

         The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

              (1) Each Global Security authenticated under this Indenture shall
         be registered in the name of the Depositary designated for such Global
         Security or a nominee thereof and delivered to such Depositary or a
         nominee thereof or custodian therefor, and each such Global Security
         shall constitute a single Security for all purposes of this Indenture.

              (2) Notwithstanding any other provision in this Indenture, no
         Global Security may be exchanged in whole or in part for Securities
         registered, and no transfer of a Global Security in whole or in part
         may be registered, in the name of any Person other than the Depositary
         for such Global Security or a nominee thereof unless (A) such
         Depositary has notified the Company that it is unwilling or unable to
         continue as Depositary for such Global Security or (ii) has ceased to
         be a clearing agency registered under the Exchange Act, (B) there shall
         have occurred and be continuing an Event of Default with respect to
         such Global Security or (C) there shall exist such circumstances, if
         any, in addition to or in lieu of the foregoing as have been specified
         for this purpose as contemplated by Section 301.

              (3) Subject to Clause (2) above, any exchange of a Global Security
         for other Securities may be made in whole or in part, and all
         Securities issued in exchange for a Global Security or any portion
         thereof shall be registered in such names as the Depositary for such
         Global Security shall direct.

              (4) Every Security authenticated and delivered upon registration
         of transfer of, or in exchange for or in lieu of, a Global Security or
         any portion thereof, whether pursuant to this Section, Section 304,
         306, 906 or 1107 or otherwise, shall be authenticated and delivered in
         the form of, and shall be, a Global Security, unless such 



                                       25
   34

         Security is registered in the name of a Person other than the 
         Depositary for such Global Security or a nominee thereof.

Section 306.      Mutilated, Destroyed Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

Section 307.      Payment of Interest; Interest Rights Preserved.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

         Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall 



                                       26
   35

forthwith cease to be payable to the Holder on the relevant Regular Record Date
by virtue of having been such Holder, and such Defaulted Interest may be paid by
the Company, at its election in each case, as provided in Clause (1) or (2)
below:

              (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on a Special Record Date for the payment of such
         Defaulted Interest, which shall be fixed in the following manner. The
         Company shall notify the Trustee in writing of the amount of Defaulted
         Interest proposed to be paid on each Security of such series and the
         date of the proposed payment, and at the same time the Company shall
         deposit with the Trustee an amount of money equal to the aggregate
         amount proposed to be paid in respect of such Defaulted Interest or
         shall make arrangements satisfactory to the Trustee for such deposit
         prior to the date of the proposed payment, such money when deposited to
         be held in trust for the benefit of the Persons entitled to such
         Defaulted Interest as in this Clause provided. Thereupon the Trustee
         shall fix a Special Record Date for the payment of such Defaulted
         Interest which shall be not more than 15 days and not less than 10 days
         prior to the date of the proposed payment and not less than 10 days
         after the receipt by the Trustee of the notice of the proposed payment.
         The Trustee shall promptly notify the Company of such Special Record
         Date and, in the name and at the expense of the Company, shall cause
         notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor to be given to each Holder of Securities
         of such series in the manner set forth in Section 106, not less than 10
         days prior to such Special Record Date. Notice of the proposed payment
         of such Defaulted Interest and the Special Record Date therefor having
         been so mailed, such Defaulted Interest shall be paid to the Persons in
         whose names the Securities of such series (or their respective
         Predecessor Securities) are registered at the close of business on such
         Special Record Date and shall no longer be payable pursuant to the
         following Clause (2).

              (2) The Company may make payment of any Defaulted Interest on the
         Securities of any series in any other lawful manner not inconsistent
         with the requirements of any securities exchange on which such
         Securities may be listed, and upon such notice as may be required by
         such exchange, if, after notice given by the Company to the Trustee of
         the proposed payment pursuant to this Clause, such manner of payment
         shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

Section 308.      Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such 



                                       27
   36

Security is registered as the owner of such Security for the purpose of
receiving payment of principal of and any premium and (subject to Section 307)
any interest on such Security and for all other purposes whatsoever, whether or
not such Security be overdue, and neither the Company, the Trustee nor any agent
of the Company or the Trustee shall be affected by notice to the contrary.

Section 309.      Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and, if not already cancelled, shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and may deliver to the Trustee (or to any
other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of as
directed by a Company Order.

Section 310.      Computation of Interest.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.


                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

Section 401.      Satisfaction and Discharge of Indenture.

         This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for), and the Trustee, upon Company Request and at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

              (1) either

                   (A) all Securities theretofore authenticated and delivered
              (other than (i) Securities which have been destroyed, lost or
              stolen and which have been replaced or paid as provided in Section
              306 and (ii) Securities for whose payment money has theretofore
              been deposited in trust or segregated and held in trust by the
              Company and thereafter repaid to the Company or discharged from
              such trust, as 



                                       28
   37

              provided in Section 1003) have been delivered to the Trustee 
              cancelled or for cancellation; or

                  (B) all such Securities not theretofore delivered to the
              Trustee cancelled or for cancellation

                       (i)   have become due and payable, or

                       (ii)  will become due and payable at their Stated 
                  Maturity within one year, or

                       (iii) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at
                  the expense, of the Company,

                  and the Company, in the case of (i), (ii) or (iii) above, has
                  deposited or caused to be deposited with the Trustee as trust
                  funds in trust for the purpose money in an amount sufficient
                  to pay and discharge the entire indebtedness on such
                  Securities not theretofore delivered to the Trustee cancelled
                  or for cancellation, for principal and any premium and
                  interest to the date of such deposit (in the case of
                  Securities which have become due and payable) or to the Stated
                  Maturity or Redemption Date, as the case may be;

              (2) the Company has paid or caused to be paid all other sums
         payable hereunder by the Company; and

              (3) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

Section 402.      Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may


                                       29
   38

determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                  ARTICLE FIVE

                                    REMEDIES

Section 501.      Events of Default.

         "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

              (1) default in the payment of any interest upon any Security of
         that series when it becomes due and payable, and continuance of such
         default for a period of 30 days; or

              (2) default in the payment of the principal of or any premium on
         any Security of that series at its Maturity; or

              (3) default in the deposit of any sinking fund payment, when and
         as due by the terms of a Security of that series; or

              (4) default in the performance, or breach, of any covenant or
         warranty of the Company in this Indenture (other than a covenant or
         warranty a default in the performance or the breach of which is
         specifically dealt with elsewhere in this Section or which has
         expressly been included in this Indenture solely for the benefit of
         series of Securities other than that series), and continuance of such
         default or breach for a period of 60 days after there has been given,
         by registered or certified mail to the Company by the Trustee or to the
         Company and the Trustee by the Holders of at least 10% in principal
         amount of the Outstanding Securities of that series a written notice
         specifying such default or breach and requiring it to be remedied and
         stating that such notice is a "Notice of Default" hereunder; or

              (5) a default under any Obligation by the Company or any
         Subsidiary (including a default with respect to Securities of any
         series other than that series) having an aggregate principal amount
         outstanding of at least $5,000,000, or under any mortgage, indenture or
         instrument (including this Indenture) under which there may be issued
         or by which there may be secured or evidenced any Obligation by the
         Company or any Subsidiary having an aggregate principal amount
         outstanding of at least $5,000,000, whether such Obligation now exists
         or shall hereafter be created, which default (A) shall constitute a
         failure to pay any portion of such Obligation when due and payable
         after the expiration of any applicable grace period with respect
         thereto or (B) shall have resulted in 



                                       30
   39

         such Obligation becoming or being declared due and payable prior to the
         date on which it would otherwise have become due and payable, without,
         in the case of Clause (A), such Obligation having been discharged or
         without, in the case of Clause (B), such Obligation having been
         discharged or such acceleration having been rescinded or annulled, in
         each such case, within a period of 10 days after there shall have been
         given, by registered or certified mail to the Company by the Trustee or
         to the Company and the Trustee by the Holders of at least 10% in
         principal amount of the Outstanding Securities of that series a written
         notice specifying such default and requiring the Company to cause such
         Obligation to be discharged or cause such acceleration to be rescinded
         or annulled, as the case may be, and stating that such notice is a
         "Notice of Default" hereunder; provided, however, that, subject to the
         provisions of Sections 601 and 602, the Trustee shall not be deemed to
         have knowledge of such default unless either (A) a Responsible Officer
         of the Trustee shall have actual knowledge of such default or (B) the
         Trustee shall have received written notice thereof from the Company,
         from any Holder, from the holder of any such Obligation or from the
         trustee under any such mortgage, indenture or other instrument; or

              (6) the entry by a court having jurisdiction in the premises of
         (A) a decree or order for relief in respect of the Company or any
         Significant Subsidiary in an involuntary case or proceeding under any
         applicable Federal or State bankruptcy, insolvency, reorganization or
         other similar law or (B) a decree or order adjudging the Company or any
         Significant Subsidiary bankrupt or insolvent, or approving as properly
         filed a petition seeking reorganization, arrangement, adjustment or
         composition of or in respect of the Company or any Significant
         Subsidiary under any applicable Federal or State law, or appointing a
         custodian, receiver, liquidator, assignee, trustee, sequestrator or
         other similar official of the Company or any Significant Subsidiary or
         of any substantial part of its property, or ordering the winding up or
         liquidation of its affairs, and the continuance of any such decree or
         order for relief or any such other decree or order unstayed and in
         effect for a period of 60 consecutive days; or

              (7) the commencement by the Company or any Significant Subsidiary
         of a voluntary case or proceeding under any applicable Federal or State
         bankruptcy, insolvency, reorganization or other similar law or of any
         other case or proceeding to be adjudicated a bankrupt or insolvent, or
         the consent by it to the entry of a decree or order for relief in
         respect of the Company or any Significant Subsidiary in an involuntary
         case or proceeding under any applicable Federal or State bankruptcy,
         insolvency, reorganization or other similar law or to the commencement
         of any bankruptcy or insolvency case or proceeding against it, or the
         filing by it of a petition or answer or consent seeking reorganization,
         arrangement, adjustment or composition of or in respect of the Company
         or any Significant Subsidiary under any applicable Federal or State
         law, or the consent by it to the filing of such petition or to the
         appointment of or taking possession by a custodian, receiver,
         liquidator, assignee, trustee, sequestrator or other similar official
         of the Company or any Significant Subsidiary or of any substantial part
         of its property, or the making by it of an assignment for the benefit
         of creditors, or the admission by it in writing of its inability to pay
         its debts generally as they become due, or 



                                       31
   40

         the taking of corporate action by the Company or any Significant
         Subsidiary in furtherance of any such action; or

              (8) any other Event of Default provided with respect to Securities
         of that series.

Section 502.      Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default (other than an Event of Default specified in
Section 501(6) or 501(7)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 501(6)
or 501 (7) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of all the Securities of that series (or, if any
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified by the terms
thereof) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, become immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

              (1) the Company has paid or deposited with the Trustee a sum
         sufficient to pay all

                       (A) overdue interest on all Securities of that series,

                       (B) the principal of (and premium, if any, on) any
            Securities of that series which have become due otherwise than by
            such declaration of acceleration and any interest thereon at the
            rate or rates prescribed therefor in such Securities,

                       (C) to the extent that payment of such interest is
            lawful, interest upon overdue interest at the rate or rates
            prescribed therefor in such Securities, and

                       (D) all sums paid or advanced by the Trustee hereunder
            and the reasonable compensation, expenses, disbursements and
            advances of the Trustee, its agents and counsel;

                                       32
   41

              and

              (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

Section 503.    Collection of Indebtedness and Suits for Enforcement by Trustee.

         The Company covenants that if

              (1) default is made in the payment of any interest on any Security
         when such interest becomes due and payable and such default continues
         for a period of 30 days, or

              (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

Section 504.    Trustee May File Proofs of Claim.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
(irrespective of whether the principal of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand for overdue principal or
interest) 



                                       33
   42

shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

Section 505.      Trustee May Enforce Claims Without Possession of Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery shall after provision for the
payment of the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, be for the ratable benefit of the Holders
of the Securities in respect of which such judgment has been recovered.

Section 506.      Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

                  First:  To the payment of all amounts due the Trustee under 
         Section 607; and

                  Second: To the payment of the amounts then due and unpaid for
         principal of and any premium and interest on the Securities in respect
         of which or for the benefit of which such money has been collected,
         ratably, without preference or priority of any kind, according to the
         amounts due and payable on such Securities for principal and any
         premium and interest, respectively.



                                       34
   43

Section 507.      Limitation on Suits.

         No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless

              (1) such Holder has previously given written notice to the Trustee
         of a continuing Event of Default with respect to the Securities of that
         series;

              (2) the Holders of not less than 25% in principal amount of the
         Outstanding Securities of that series shall have made written request
         to the Trustee to institute proceedings in respect of such Event of
         Default in its own name as Trustee hereunder;

              (3) such Holder or Holders have offered to the Trustee reasonable
         indemnity against the costs, expenses and liabilities to be incurred in
         compliance with such request;

              (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

              (5) no direction inconsistent with such written request has been
         given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of that
         series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

Section 508.      Unconditional Right of Holders to Receive Principal Premium 
                  and Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional to
receive payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

Section 509.      Restoration of Rights and Remedies.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights



                                       35
   44

and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.


Section 510.      Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 511.      Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

Section 512.      Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that

              (1) such direction shall not be in conflict with any rule of law
         or with this Indenture, and

              (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

Section 513.      Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

              (1) in the payment of the principal of or any premium or interest
         on any Security of such series, or



                                       36
   45

              (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security of such series affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

Section 514.      Undertaking for Costs.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company.

Section 515.      Waiver of Usury, Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                  ARTICLE SIX

                                   THE TRUSTEE

Section 601.      Certain Duties and Responsibilities.

              (1) Except during the continuance of an Event of Default,

                  (A) the Trustee undertakes to perform such duties and only
              such duties as are specifically set forth in this Indenture, and
              no implied covenants or obligations shall be read into this
              Indenture against the Trustee; and

                  (B) in the absence of bad faith on its part, the Trustee may
              conclusively rely, as to the truth of the statements and the
              correctness of the opinions expressed therein, upon certificates
              or opinions furnished to the Trustee and conforming to the
              requirements of this Indenture; but in the case of any such
              certificates or

              opinions which by any provision hereof are specifically required
              to be furnished to the Trustee, the Trustee shall be under a duty
              to examine the same to determine whether or not they conform to
              the requirements of this Indenture.

              (2) In case an Event of Default has occurred and is continuing,
         the Trustee shall exercise such of the rights and powers vested in it
         by this Indenture, and use the same degree of care and skill in their
         exercise, as a prudent man would exercise under the circumstances in
         the conduct of his own affairs.

              (3) No provision of this Indenture shall be construed to relieve
         the Trustee from liability for its own negligent action, its own
         negligent failure to act, or its own willful misconduct, except that

                  (A) this Subsection shall not be construed to limit the effect
              of Subsection (1) of this Section;

                  (B) the Trustee shall not be liable for any error of judgment
              made in good faith by a Responsible Officer, unless it shall be
              proved that the Trustee was negligent in ascertaining the
              pertinent facts;

                  (C) the Trustee shall not be liable with respect to any action
              taken or omitted to be taken by it in good faith in accordance
              with the direction of the Holders of a majority in principal
              amount of the Outstanding Securities relating to the time, method
              and place of conducting any proceeding for any remedy available to
              the Trustee, or exercising any trust or power conferred upon the
              Trustee, under this Indenture; and

                  (D) no provision of this Indenture shall require the Trustee
              to expend or risk its own funds or otherwise incur any financial
              Liability in the performance of any of its duties hereunder, or in
              the exercise of any of its rights and powers, if it shall have
              reasonable grounds for believing that repayment of such funds or
              adequate indemnity against such risk or liability is not
              reasonably assured to it.

              (4) Whether or not therein expressly so provided, every provision
         of this Indenture relating to the conduct or affecting the liability of
         or affording protection to the Trustee shall be subject to the
         provisions of this Section.

Section 602.      Notice of Defaults.

         Within 90 days after the occurrence of any default hereunder, the
Trustee shall transmit by mail to all Holders of Securities, as their names and
addresses appear in the Security Register, notice of such default hereunder
known to the Trustee, unless such default shall have been cured or waived;
provided, however, that, except in the case of a default in the payment of the
principal of (or premium, if any) or interest on any Securities or in the
payment of any sinking or purchase fund installment, the Trustee shall be
protected in withholding such notice if and so long as the 



                                       38
   47


board of directors, the executive committee or a trust committee of directors
and/or Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interests of the Holders of Securities; and
provided, further, that in the case of any default of the character specified in
Section 501(4) no such notice to Holders of Securities shall be given until at
least 30 days after the occurrence thereof. For the purpose of this Section, the
term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default.

Section 603.      Certain Rights of Trustee.

         Subject to the provisions of Section 601:

              (1) the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other

              (3) whenever in the administration of this Indenture the Trustee
         shall deem it desirable that a matter be proved or established prior to
         taking, suffering or omitting any action hereunder, the Trustee (unless
         other evidence be herein specifically prescribed) may, in the absence
         of bad faith on its part, rely upon an Officers' Certificate;

              (4) the Trustee may consult with counsel and the written advice of
         such counsel or any Opinion of Counsel shall be full and complete
         authorization and protection in respect of any action taken, suffered
         or omitted by it hereunder in good faith and in reliance thereon;

              (5) the Trustee shall be under no obligation to exercise any of
         the rights or powers vested in it by this Indenture at the request or
         direction of any of the Holders pursuant to this Indenture, unless such
         Holders shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction;

              (6) the Trustee shall not be bound to make any investigation into
         the facts or matters stated in any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document, but the Trustee, in its discretion, may make such
         further inquiry or investigation into such facts or matters as it may
         see fit, and, if the Trustee shall determine to make such further
         inquiry or investigation, it shall be entitled to


                                       39
   48

        
         examine the books, records and premises of the Company, personally or
         by agent or attorney; and

              (7) the Trustee may execute any of the trusts or powers hereunder
         or perform any duties hereunder either directly or by or through agents
         or attorneys and the Trustee shall not be responsible for any
         misconduct or negligence on the part of any agent or attorney appointed
         with due care by it hereunder.

Section 604.      Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.

Section 605.      May Hold Securities.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

Section 606.      Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company.

Section 607.      Compensation and Reimbursement.

         The Company agrees

              (1) to pay to the Trustee from time to time reasonable
         compensation for all services rendered by it hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

              (2) except as otherwise expressly provided herein, to reimburse
         the Trustee upon its request for all reasonable expenses, disbursements
         and advances incurred or made by the Trustee in accordance with any
         provision of this Indenture (including the reasonable compensation and
         the expenses and disbursements of its agents and counsel), except any
         such expense, disbursement or advance as may be attributable to its
         negligence or bad faith; and

                                       40
   49

              (3) to indemnify the Trustee for, and to hold it harmless against,
         any loss, liability or expense incurred without negligence or bad faith
         on its part, arising out of or in connection with the acceptance or
         administration of the trust or trusts hereunder, including the costs
         and expenses of defending itself against any claim or liability in
         connection with the exercise or performance of any of its powers or
         duties hereunder.

                  As security for the performance of the obligations of the
         Company under this Section the Trustee shall have a lien prior to the
         Holders upon all property and funds held or collected by the Trustee as
         such, except funds held in trust for the benefit of the Holders.

Section 608.      Conflicting Interests.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.

Section 609.      Corporate Trustee Required, Eligibility.

         There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000. If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this Section
and to the extent permitted by the Trust Indenture Act, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee with respect to the Securities of any series shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

Section 610.      Resignation and Removal, Appointment of Successor.

         No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

         The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of



                                       41
   50

competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

         The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

         If at any time:

              (1) the Trustee shall fail to comply with Section 608 after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Security for at least six months, or

              (2) the Trustee shall cease to be eligible under Section 609 and
         shall fail to resign after written request therefor by the Company or
         by any such Holder, or

              (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities of which such Trustee acts as trustee, or
(B) subject to Section 514, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee with respect to all Securities of which such Trustee acts as
trustee and the appointment of a successor Trustee or Trustees.

         If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 611, any
Holder who has been a bona fide Holder of a Security of such series for at least
six months or the Trustee may, on behalf of 



                                       42
   51

himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

         The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

Section 611.      Acceptance of Appointment by Successor.

         In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges and reimbursement of its expenses (including reasonable
fees and-expenses of counsel and agents), if any, to which such retiring Trustee
is otherwise legally entitled, execute and deliver an instrument transferring to
such successor Trustee all the rights, powers and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder.

         In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; 



                                       43
   52

but, on request of the Company or any successor Trustee, such retiring Trustee
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to the Securities
of that or those series to which the appointment of such successor Trustee
relates.

         Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in the
first or second preceding paragraph, as the case may be.

         No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.

Section 612.      Merger, Conversion, Consolidation or Succession to Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

Section 613.      Preferential Collection of Claims Against Company.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

Section 614.      Appointment of Authenticating Agent.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of and subject to the direction of the Trustee to authenticate and deliver
Securities of such series issued upon original issue and upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section
306, and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation 



                                       44
   53

organized and doing business under the laws of the United States of America, any
State thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

         This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

         administration of the trusts hereunder by more than one Trustee,
         pursuant to the requirements of Section 611; or

              (9) to cure any ambiguity, to correct or supplement any provision
         herein which may be defective or inconsistent with any other provision
         herein, or to make any other provisions with respect to matters or
         questions arising under this Indenture, provided that such action
         pursuant to this Clause (9) shall not adversely affect the interests of
         the Holders of Securities of any series.

Section 902.      Supplemental Indentures with Consent of Holders.

enter into an indenture or indentures supplemental hereto for the



                                       49
   58

purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or of modifying in any manner the rights of
the Holders of Securities of such series under this Indenture; provided,
however, that no such supplemental indenture shall, without the consent of the
Holder of each Outstanding Security affected thereby,

              (1) change the Stated Maturity of the principal of, or any
         installment of principal of or interest on, any Security, or reduce the
         principal amount thereof or the rate of interest thereon or any premium
         payable upon the redemption thereof, or reduce the amount of the
         principal of an Original Issue Discount Security or any other Security
         which would be due and payable upon a declaration of acceleration of
         the Maturity thereof pursuant to Section 502, or change any Place of
         Payment where, or the coin or currency in which, any Security or any
         premium or interest thereon is payable, or impair the right to
         institute suit for the enforcement of any such payment on or after the
         Stated Maturity thereof (or, in the case of redemption, on or after the
         Redemption Date), or

              (2) reduce the percentage in principal amount of the Outstanding
         Securities of any series, the consent of whose Holders is required for
         any such supplemental indenture, or the consent of whose Holders is

         Indenture or certain defaults hereunder and their consequences)
         provided for in this Indenture, or

              (3) modify any of the provisions of this Section, Section 513 or
         Section 1009, except to increase any such percentage or to provide that
         certain other provisions of this Indenture cannot be modified or waived
         without the consent of the Holder of each Outstanding Security affected
         thereby; provided, however, that this clause shall not be deemed to
         require the consent of any Holder with respect to changes in the
         references to "the Trustee" and concomitant changes in this Section and
         Section 1009, or the deletion of this proviso, in accordance with the
         requirements of Sections 611 and 901(8).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

Section 903.      Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,

Opinion of Counsel stating that the execution of such supplemental indenture is


                                       50
   59

authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

Section 904.      Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental

if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

                                  COVENANTS

Section 1001.     Payment of Principal, Premium and Interest.

         The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

Section 1002.     Maintenance of Office or Agency.

         The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served 



                                       51
   60

at the Corporate Trust Office of the Trustee, and the Company hereby appoints
the Trustee as its agent to receive all such presentations, surrenders, notices
and demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

Section 1003.     Money for Securities Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

         The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from an further liability with respect to
such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Security



                                       52
   61

of any series and remaining unclaimed for two years after such principal,
premium or interest has become due and payable shall be paid to the Company on
Company Request, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in the Borough of Manhattan, The City of
New York, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

Section 1004.     Statement by Officers as to Default.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

Section 1005.     Existence.

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence,
rights (charter and statutory) and franchises; provided, however, that the
Company shall not be required to preserve any such right or franchise if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

Section 1006.     Maintenance of Properties.

         The Company will cause all properties used or useful in the conduct of
its business or the business of any Subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Company, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

         The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a lien upon the property of the Company or any Subsidiary; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

Section 1008.     Limitation on Liens on Stock or Indebtedness of Significant 
                  Subsidiary.

         The Company will not, and will not permit any Significant Subsidiary
to, create, assume, incur or suffer to exist any Lien upon any stock or
indebtedness, whether owned on the date of this Indenture or hereafter acquired,
of any Significant Subsidiary (other than a Significant Subsidiary, the stock or
indebtedness of which at the date of the issuance of any series of Securities is
subject to a Lien or is required to be subject to a Lien) to secure any
Obligation (other than the Securities) of the Company, any Subsidiary or any
other Person without in any such case making effective provision whereby all of
the Outstanding Securities shall be directly secured equally and ratably with
such Obligation, excluding, however, from the operation of the foregoing
provisions of this Section 1008 any Lien upon stock or indebtedness of any
corporation existing at the time such corporation becomes a Significant
Subsidiary or existing or created upon stock or indebtedness of a Significant
Subsidiary at the time of acquisition of such stock or indebtedness and any
extension, renewal or replacement (or successive extensions, renewals or
replacements) in whole or in part of any such Lien; provided, however, that the
principal amount of the Obligation secured thereby shall not exceed the
principal amount of the Obligation so secured at the time of such extension,
renewal or replacement; and provided, further, that such Lien shall be limited
to all or such part of the stock or indebtedness which secured the Lien so
extended, renewed or replaced.

Section 1009.     Waiver of Certain Covenants.

         Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 301(18),
901(2) or 901(7) for the benefit of the Holders of such series or in Section
1008, if before the time for such compliance the Holders of at least 66 2/3% in
principal amount of the Outstanding Securities of such series shall, by Act of
such Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Company and the duties of the Trustee in respect of any such term,
provision or condition shall remain in fall force and effect.

Section 1101.     Applicability of Article.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

Section 1102.     Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution or in another manner specified as contemplated by Section
301 for such Securities. In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 60
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

Section 1103.     Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of a portion of the principal amount of any Security of such series,
provided that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to be
redeemed.

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

Section 1104.     Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

         All notices of redemption shall state:

              (1) the Redemption Date,

              (2) the Redemption Price,

              (3) if less than all the Outstanding Securities of any series
         consisting of more than a single Security are to be redeemed, the
         identification (and, in the case of partial redemption of any such
         Securities, the principal amounts) of the particular Securities to be
         redeemed and, if less than all the Outstanding Securities of any series
         consisting of a single Security are to be redeemed, the principal
         amount of the particular Security to be redeemed,

              (4) that on the Redemption Date the Redemption Price will become
         due and payable upon each such Security to be redeemed and, if
         applicable, that interest thereon will cease to accrue on and after
         said date,

              (5) the place or places where each such Security is to be
         surrendered for payment of the Redemption Price, and

              (6) that the redemption is for a sinking fund, if such is the
         case.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.

Section 1105.     Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

Section 1106.     Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

Section 1107.     Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series and of like tenor, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.


                                 ARTICLE TWELVE

                                  SINKING FUNDS

Section 1201.     Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.



                                       57

         The minimum amount of any sinking fund payment provided for by the
terms of any Securities is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of such Securities is herein referred to as an "optional sinking fund
payment". If provided for by the terms of any Securities, the cash amount of any
sinking fund payment may be subject to reduction as provided in Section 1202.
Each sinking fund payment shall be applied to the redemption of Securities as
provided for by the terms of such Securities.

Section 1202.     Satisfaction of Sinking Fund Payments with Securities.

         The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

Section 1203.     Redemption of Securities for Sinking Fund.

         Not less than 90 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 60 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.


                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

Section 1301.     Company's Option to Effect Defeasance or Covenant Defeasance.

         The Company may elect, at its option at any time, to have Section 1302
or Section 1303 applied to any Securities or any series of Securities, as the
case may be, designated pursuant to Section 301 as being defeasible pursuant to
such Section 1302 or 1303, in accordance with any 



                                       58
   67

applicable requirements provided pursuant to Section 301 and upon compliance
with the conditions set forth below in this Article. Any such election shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities.

Section 1302.     Defeasance and Discharge.

         Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by such
Securities and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: (1) the rights of Holders of such Securities to
receive, solely from the trust fund described in Section 1304 and as more fully
set forth in such Section, payments in respect of the principal of and any
premium and interest on such Securities when payments are due, (2) the Company's
obligations with respect to such Securities under Sections 304, 305, 306, 1002
and 1003, (3) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (4) this Article. Subject to compliance with this Article, the
Company may exercise its option (if any) to have this Section applied to any
Securities notwithstanding the prior exercise of its option (if any) to have
Section 1303 applied to such Securities.

Section 1303.     Covenant Defeasance.

         Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Section 801(3),
Sections 1006 through 1008, inclusive, and any covenants provided pursuant to
Section 301(18), 901(2) or 901(7) for the benefit of the Holders of such
Securities and (2) the occurrence of any event specified in Sections 501(4)
(with respect to any of Section 801(3), Sections 1006 through 1008, inclusive,
and any such covenants provided pursuant to Section 301(18), 901(2) or 901(7)),
501(5) and 501(8) shall be deemed not to be or result in an Event of Default, in
each case with respect to such Securities as provided in this Section on and
after the date the conditions set forth in Section 1304 are satisfied
(hereinafter called "Covenant Defeasance"). For this purpose, such Covenant
Defeasance means that, with respect to such Securities, the Company may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such specified Section (to the extent so specified
in the case of Section 501(4)), whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or by reason of any reference in
any such Section to any other provision herein or in any other document, but the
remainder of this Indenture and such Securities shall be unaffected thereby.

Section 1304.     Conditions to Defeasance or Covenant Defeasance.

         The following shall be the conditions to the application of Section
1302 or Section 1303 to- any Securities or any series of Securities, as the case
may be:

              (1) The Company shall irrevocably have deposited or caused to be
         deposited with the Trustee (or another trustee which satisfies the
         requirements contemplated by Section 609 and agrees to comply with the
         provisions of this Article applicable to it) as trust funds in trust
         for the purpose of making the following payments, specifically pledged
         as security for, and dedicated solely to, the benefits of the Holders
         of such Securities, (A) money in an amount, or (B) U.S. Government
         Obligations which through the scheduled payment of principal and
         interest in respect thereof in accordance with their terms will
         provide, not later than one day before the due date of any payment,
         money in an amount, or (C) a combination thereof, in each case
         sufficient, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge, and which shall
         be applied by the Trustee (or any such other qualifying trustee) to pay
         and discharge, the principal of and any premium and interest on such
         Securities on the respective Stated Maturities, in accordance with the
         terms of this Indenture and such Securities. As used herein, "U.S.
         Government Obligation" means (x) any security which is (i) a direct
         obligation of the United States of America for the payment of which the
         full faith and credit of the United States of America is pledged or
         (ii) an obligation of a Person controlled or supervised by and acting
         as an agency or instrumentality of the United States of America the
         payment of which is unconditionally guaranteed as a full faith and
         credit obligation by the United States of America, which, in either
         case (i) or (ii), is not callable or redeemable at the option of the
         issuer thereof and (y) any depositary receipt issued by a bank (as
         defined in Section 3(a)(2) of the Securities Act) as custodian with
         respect to any U.S. Government Obligation which is specified in Clause
         (x) above and held by such bank for the account of the holder of such
         depositary receipt, or with respect to any specific payment of
         principal of or interest on any U.S. Government Obligation which is so
         specified and held, provided that (except as required by law) such
         custodian is not authorized to make any deduction from the amount
         payable to the holder of such depositary receipt from any amount
         received by the custodian in respect of the U.S. Government Obligation
         or the specific payment of principal or interest evidenced by such
         depositary receipt.

              (2) In the event of an election to have Section 1302 apply to any
         Securities or any series of Securities, as the case may be, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (A) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling or (B) since the date of this
         instrument, there has been a change in the applicable Federal income
         tax law, in either case (A) or (B) to the effect that, and based
         thereon such opinion shall confirm that, the Holders of such Securities
         will not recognize gain or loss for Federal income tax purposes as a
         result of the deposit, Defeasance and discharge to be effected with
         respect to such Securities and will be subject to Federal income tax on
         the same amount, in the same 



                                       60
   69

         manner and at the same times as would be the case if such deposit, 
         Defeasance and discharge were not to occur.

              (3) In the event of an election to have Section 1303 apply to any
         Securities or any series of Securities, as the case may be, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holders of such Securities will not recognize gain or loss for
         Federal income tax purposes as a result of the deposit and Covenant
         Defeasance to be effected with respect to such Securities and will be
         subject to Federal income tax on the same amount, in the same manner
         and at the same times as would be the case if such deposit and Covenant
         Defeasance were not to occur.

              (4) The Company shall have delivered to the Trustee an Officer's
         Certificate to the effect that neither such Securities nor any other
         Securities of the same series, if then listed on any securities
         exchange, will be delisted as a result of such deposit.

              (5) No event which is, or after notice or lapse of time or both
         would become, an Event of Default with respect to such Securities or
         any other Securities shall have occurred and be continuing at the time
         of such deposit or, with regard to any such event specified in Sections
         501(6) and (7), at any time on or prior to the 90th day after the date
         of such deposit (it being understood that this condition shall not be
         deemed satisfied until after such 90th day).

              (6) Such Defeasance or Covenant Defeasance shall not cause the
         Trustee to have a conflicting interest within the meaning of the Trust
         Indenture Act (assuming all Securities are in default within the
         meaning of such Act).

              (7) Such Defeasance or Covenant Defeasance shall not result in a
         breach -or violation of, or constitute a default under, any other
         agreement or instrument to which the Company is a party or by which it
         is bound.

              (8) Such Defeasance or Covenant Defeasance shall not result in the
         trust arising from such deposit constituting an investment company
         within the meaning of the Investment Company Act unless such trust
         shall be registered under such Act or exempt from registration
         thereunder.

              (9) The Company shall have delivered to the Trustee an Officer's
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent with respect to such Defeasance or Covenant Defeasance have
         been complied with.

Section 1305.     Deposited Money and U.S. Government obligations to Be Held in 
                  Trust; Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (solely for purposes of this
Section and Section 1306, the Trustee and any such 



                                       61
   70

other trustee are referred to collectively as the "Trustee") pursuant to Section
1304 in respect of any Securities shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums, due and to become due
thereon in respect of principal and any premium and interest, but money so held
in trust need not be segregated from other funds except to the extent required
by law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

Section 1306.     Reinstatement.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305 with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.


                                ---------------
